Abstract
Official abstract text for this publication.
A sheet manufacturing apparatus includes a web forming unit that forms a web in which at least fiber and resin are deposited in the air; a pressing unit that presses the web; and a heating and pressing unit that heats and presses the web on a further downstream side than the pressing unit in a transport direction of the web, in which a pressing force of the pressing unit is greater than a pressing force of the heating and pressing unit.
First claim
Opening claim text (preview).
1 . A sheet manufacturing apparatus comprising: a web forming unit that forms a web in which at least fiber and resin are deposited in the air; a pressing unit that presses the web; and a heating and pressing unit that heats and presses the web on a further downstream side than the pressing unit in a transport direction of the web, wherein a pressing force of the pressing unit is greater than a pressing force of the heating and pressing unit. 2 . The sheet manufacturing apparatus according to claim 1 , wherein the pressing unit has at least a pair of pressing rollers for pressing the web by pinching the web by the pair of the rollers, and wherein the heating and pressing unit has at least a pair of heating and pressing rollers for heating and pressing the web by pinching the web by the pair of the rollers. 3 . The sheet manufacturing apparatus according to claim 1 , wherein a diameter of the pressing roller is greater than a diameter of the heating and pressing roller. 4 . The sheet manufacturing apparatus according to claim 2 , wherein a member that is able to come into contact with the web between the pressing rollers and the heating and pressing rollers is only a web receiving member that is able to receive the web from below. 5 . A sheet manufacturing method comprising: a web forming step of forming a web in which at least fiber and resin are deposited in the air; a pressing step of pressing the web; and a heating step of heating and pressing the web after the pressing step, wherein a pressing force in the pressing step is greater than a pressing force in the heating and pressing step. 6 . A sheet manufacturing apparatus comprising: a web forming unit that forms a web in which at least fiber and resin are deposited in the air; a pressing unit that presses the web at 51 N to 306 N; and a heating and pressing unit that heats and presses the web on a further downstream side than the pressing unit in a transport direction of the web.
